Yes, I have Leonard. Took them off to clean and sand the scales down a bit. Deep scratches and a cupped shaped 45-degree edge with dings in the edge of the scales. Here is one sanded at 400grit. No extra letters or stamps in the scales and you can see that this is not just a black plastic. It has a very light smell of rubber but not as strong as some rubber scales I've sanded and the color of the dust is a yellowish brown. What is this material? Anyone?
